Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator.

Conventional refrigerators have a cooler chamber in which a cooler, a blower, and the like are provided through a fan guard, a partition plate, and the like behind the freezer compartment. Typically, the depth dimension of this cooler chamber is approximately close to the thickness of the cooler, and the width and height dimensions are the same as the rear portion (back plate portion) in the freezer compartment. In recent years, with the increase in size of the refrigerator, the cooler also tends to increase in size, but the width of the freezer compartment (cooling chamber) is significantly larger than that of the cooler.

For example, when the thickness of the cooler is 50 mm to 100 mm, the depth of the cooler chamber is almost 50 mm to 100 mm or more. The width dimension is the total width of the back plate portion inside the freezer compartment.

However, since the width of the cooler did not increase following this, the side of the cooler was covered with a partition member or filled with a heat insulator so that air flowed into the cooler, thus part of the volume of the refrigerator was wasted.

In the structure of patent document 1, both sides of a cooler become wasteful. In addition, Patent Document 1 covers a periphery of a cooler, configures a cooler chamber, arranges a blower above the cooler chamber, and forms a cold air passage for blowing cold air to the refrigerating chamber on the back side of the cooler chamber. The cold air from the cold air passage is discharged into the refrigerating chamber from the cold air discharge port located in the rear side of the refrigerating chamber, and is configured to return the food in the refrigerating chamber to the cooler from the hole formed in the upper surface in front of the refrigerating chamber.

In the refrigerator disclosed in Patent Document 2, a cooler and a cooling chamber accommodating the cooler are provided in a second partition wall insulated and partitioned between the freezer compartment and the intermediate storage chamber, and the main blower is placed in the main blower chamber behind the cooling chamber. The secondary blower is installed in the secondary blower chamber located on the rear side of the storage compartment.

The secondary blower blows out the cold air toward the front (door side) from the inside (back wall) discharge port of the storage space of the refrigerator.

Next, in the refrigerator disclosed in Patent Document 3, a blower and a damper are provided in the rear space of each chamber of the refrigerator having a freezer compartment, a temperature conversion chamber, a refrigerator compartment, and the like, and a cooler chamber is formed over the rear side space of the freezer compartment and the vegetable compartment. And a cooler is installed in the cooler chamber. The refrigerator also blows cold air toward the front (door side) from the inside (back wall) of the storage space of the refrigerator by a blower provided in the back space of each chamber.

The refrigerator is provided with a refrigerator compartment blower in a space on the rear side of the refrigerator compartment, and a refrigerator compartment damper is installed in the refrigerator compartment.

In addition, the refrigerator disclosed in Patent Document 4 partitions between a freezer compartment and a cooler chamber with a partition plate, and installs a cooler, a freezer blower and a refrigerator blower in the cooler chamber, and the freezer compartment discharges the freezer cold air installed in the partition plate. The cold air blower which blows cold air from the air blower using a freezer compartment blower, and returns to the lower part of the cooler from the freezer cool air return blower.

In the refrigerating chamber, the cold air is blown out from the cold air spout provided in the entire inner portion (back wall portion) of the refrigerating chamber storage space, and a cold air path is returned to the suction port provided at the front of the partition wall separating the freezer compartment and the refrigerating compartment. .

Japanese Patent No. 3073636 Japanese Utility Model Publication No. 61-35910 Japanese Patent No. 4357448 Japanese Patent No. 2922129

In the refrigerators disclosed in Patent Documents 1 to 4, since the cold air is discharged from the cold air outlet of the refrigerating compartment rear part to the cold compartment, the cold air is hardly reached by the food in the vicinity of the cold air outlet and reaching the food in the front part of the cold compartment. For this reason, when it flows in the vicinity of a door pocket, the food in a refrigerator compartment is cooled and the temperature of cold air rises, and cooling of the food of the front part of a refrigerator compartment and the food accommodated in the door pocket cannot be cooled in a short time. In addition, the part where the door and the refrigerator contact each other is heated by heat conduction of air outside the refrigerator. For this reason, in the season and environment where the temperature of the air outside the refrigerator is high, the temperature inside the refrigerator near the door and the refrigerator is likely to be higher than other parts. In addition, Patent Documents 1 to 3 have the following characteristics.

In the refrigerator disclosed in Patent Document 1, the volume of both sides of the cooler is wasted, and a cold air passage for blowing cold air to the cold storage chamber is formed on the rear side of the cooler chamber, so that in addition to the depth dimension of the cooler chamber, It becomes larger by the depth dimension.

The refrigerator disclosed in patent document 2 is a refrigerator which installs a cooler etc. in the 2nd partition wall which partitions a freezer compartment and the storage chamber below a freezer compartment. This type of refrigerator can be widely used in the depth direction because the depth direction in the freezing chamber is increased, but the dimension in the vertical direction of the chamber located in the upper and lower portions in the second partition wall is reduced. In this case, since the food stored in the inside is difficult to be taken out by the food in the front side, when it is wide in the depth direction, adoption is avoided in view of practical efficiency considering practical use. In particular, in a refrigerator in which one side of the second partition wall becomes a refrigerator compartment or the like, since the temperature difference from the freezer compartment is large, it is necessary to secure the thickness of the heat insulation wall largely, and the efficiency of securing the interior is low.

In the refrigerator disclosed in Patent Document 3, the inside of the refrigerating compartment cannot be used effectively on the back side of the refrigerating compartment by the volume of the refrigerating compartment blower.

In view of the above problems, an object of the present invention is to provide a refrigerator capable of shortening the cooling time of a food installed or stored in a door pocket and cooling efficiently at a predetermined temperature.

In order to solve the said subject, the structure described in a claim is employ | adopted, for example. As an example, an adiabatic partition wall partitioning the freezer compartment and the refrigerating compartment, a freezer compartment door for opening and closing the freezer compartment, a refrigerating compartment door for opening and closing the refrigerating compartment, a cooler compartment partitioned from the freezer compartment at the rear side of the freezer compartment, and the A refrigerator having a cooler disposed in a cooler chamber, a freezer blower and a refrigerating chamber blower disposed in the cooler chamber, and a cold air passage for sending cold air from the cooler chamber to the refrigerating chamber, wherein the cold air passage is the insulating partition wall. The cool air which is formed forward from the rear part in the inside and is blown by the refrigerator compartment blower is blown from the first outlet of the front section of the cold passage through downward from the upper side of the storage section provided in the refrigerator compartment door. It is done.

According to the present invention, it is possible to provide a refrigerator capable of efficiently cooling foods installed or stored in a door pocket.

As mentioned above, the thing accommodated in the refrigerating compartment 4 is made into the whole refrigerating compartment by the cold ejected to the refrigerator compartment door pocket 7 side, and the cold air ejected from the ejection opening 25a provided in the refrigerating compartment partition plate 25. Cool so as to surround from back and forth. Thereby, it is suppressed that big influence is received by the storing position of a thing, and cooling nonuniformity becomes small and storage performance improves further.

The flow of cold air in the freezer refrigerator will be described. The cold air blown out from the cold air blower outlet 12 by the freezer blower 14 cools the inside of the freezer compartment 3 (stored food), as shown by the thick solid arrows shown in FIGS. 2, 3, and 4, The cold air circulation returned from the cold air inlet 13 to the cooler 16 is repeated. Thereby, the temperature in the freezer compartment 3 is set to room temperature.

On the other hand, the cold air ejected to the refrigerating chamber 4 side by the refrigerating chamber blower 15 is cooled by the cooler 16 and then directed to the blowing duct 17 side, as shown by the slender solid arrows in FIGS. 2 and 3. Part of the cold air enters the cold air passage 18 as a thin solid arrow through one of the openings 18a of the cold air passage, and enters the door pocket from the opening 18b of the other end of the cold air passage 18. It is ejected in the direction of (7).

The remaining cold air, as shown by the thin solid line arrow, the cold air entering the second cold air passage 23 and the refrigerating compartment cold air passage 24 from one of the openings 18a of the cold air passage, is a blowout port provided in the refrigerating compartment partition plate on the rear side of the refrigerating compartment ( It blows off from the refrigeration chamber 4 from 25a).

The cold air jetted from the jet port 18b and the jet port 25a opened at the other end of the cold channel 18 is a gap passage formed between the container 19 and the bottom portion of the inner box 2a. Inhaled at 20.

The cold passage that cooled the outer periphery of the container 19 also passes through the gap passage 20. That is, the cold air passing through the cooling gap passage 27 formed between the upper surface of the vessel 19 and the vessel cover 29 or between the vessel bottom wall 19a at the upper end and the vessel 19 at the lower end, The gap passage 20 is distributed. These cold air are returned to the cooler 16 through the refrigerating chamber return cold air passage 28.

The cold air after cooling the refrigerator compartment 4 is returned to the cooler 16 like the solid arrow shown in FIG. In the lower part of this cooler 16, the glass tube heater 31 which removes the frost attached to the cooler 6 is provided. The heat dissipation fin 32 is provided on the surface of this glass tube heater 31.

The water container 33 receives the defrost water which melt | dissolved the frost attached to the cooler 16. The cylinder part 33a penetrates through the heat insulation partition wall 9, and faces the accommodating part 34a of the drain pipe 34 for draining the said defrost water.

As shown in FIGS. 4 and 5, the return duct 35 has one end connected to the refrigerating chamber return air passage 28 and the other end inside the water container 33 (lower part of the cooler 16). Is connected to. In addition, as shown in FIG. 2, the return ducts 3 and 5 return the return coolant which rises in the refrigerating chamber return cooling air passage 28 provided in the center of the back part of the refrigerating chamber 4 to the lower surface of the cooler 16. As shown in FIG. It is a structure which returns from the back part of the water container 33 so that it may return.

Next, the flow of cold air in the freezer refrigerator according to the embodiment of the present invention will be described with reference to FIG. 6. 3 is a freezer compartment, 4 is a refrigerator compartment, 14 is a freezer blower, 15 is a refrigerator blower, and 16 is a cooler.

The electric damper 36 provided in the cooler chamber 11 shown in FIG. 3 is installed in the ventilation duct 17, adjusts the amount of cold air sent to the refrigerating chamber 4, and sets the temperature in the refrigerating chamber 4 The temperature is maintained at 3 ° C., for example.

The freezer compartment 3 flows through the cold air circulation path formed by the cold air blown by the freezer compartment blower 14 so that the cool air flows in the order of the cooler 16, the freezer compartment 3, and the cooler 16. The refrigerating chamber 4 flows through the cold air circulation path so that the cool air blown by the refrigerating chamber blower 15 flows in the order of the cooler 16, the electric damper 36, the refrigerating chamber 4, and the cooler 16. By this cold air circulation, each chamber 3 and 4 is cooled to predetermined temperature.

The electric damper 36 is provided in the ventilation duct 17 provided in the side of the cooler 16 as shown to FIG. 2, FIG. Thereby, the back plate part which comprises the inside of a refrigerator compartment is flattened, and shelf area expands.

Next, the flow in which the cold air blown from the refrigerator 15 for the refrigerator compartment cools the front part of the refrigerator compartment, especially the stored goods in the door pocket 7, is demonstrated using FIG.

Reference numeral 1 denotes a freezer refrigerator body, 3 a freezer compartment, 4 a refrigerator compartment, 7 a refrigerator compartment door pocket, 8 a reservoir tank for storing a drink, and the like, and the reservoir tank 8 may be a PET bottle. Reference numeral 14 denotes a blower for a freezer compartment, 15 a blower for a refrigerating compartment, 16 a cooler, 18 a cold air passage installed in the adiabatic partition wall 9, and 18b a cold air passage that injects cold air into the front refrigerating compartment door pocket 7. Blowout port of the opening of the other end.

The cold air ejected from the opening 18b at the other end of the cold air passage in the direction of the refrigerating compartment door pocket 7 cools the door pocket portion from above to quickly cool the beverage or the beverage in the water storage tank 8. At the same time, the cold air jetted to the door pocket 7 cools the food and the like stored in the front part of the refrigerating compartment 4.

Therefore, the food stored in the refrigerating compartment is uniformly cooled and cooled as a whole without unevenness by cold air ejected from the front and rear of the refrigerating compartment. This improves the shelf life of the food.

Next, the refrigerator compartment cooling operation | movement which becomes a freezer compartment cooling operation and an energy saving operation is demonstrated using FIG. 8 according to the outside temperature and the temperature state of each chamber.

Reference numeral 14 denotes a freezer compartment blower, 15 a refrigerator compartment blower, 16 a cooler, and 37 a compressor. The freezer compartment blower 14, the refrigerator compartment blower 15, and the compressor 37 are inverter controlled, and the rotation speed can be changed in several steps. In addition, although not shown, this refrigerator has an outside air temperature sensor, a freezer compartment temperature sensor, a refrigerator compartment temperature sensor, etc. As shown in FIG.

And this refrigeration refrigerator main body 1 is equipped with the operation modes, such as normal operation, a freezer compartment cooling operation, and a refrigerator compartment cooling operation.

Fig. 8 shows the operating states of the compressor 37, the freezer compartment blower 14, and the refrigerating compartment blower 15 in accordance with the above operation mode. In addition, the rotation speed of the compressor of FIG. 8 shows a high speed of 4300 RPM, a medium speed of 3100 RPM, and a low speed of 2200-1500 RPM.

With the above configuration, the freezer compartment can be quickly cooled at high power during the freezer compartment cooling operation, and energy-saving operation can be performed without waste due to low speed rotation in the refrigerator compartment cooling operation.

The operation states of the compressor and the blower at low load and high load will be described. In particular, the refrigerator compartment operation and frost cooling operation are demonstrated. In the figure, the vertical axis compressor, the freezer compartment blower, and the refrigerator compartment blower increase and decrease the rotational speed, and the electric damper shows opening and closing.

The rotation speed and the like of the above-described apparatus are shown how to be controlled at low load with low outside temperature and high load with high outside temperature. The refrigerator of the present embodiment can perform a refrigerator compartment operation and a frost cooling operation.

In Fig. 9, the refrigerating chamber operation is intended to reduce the rotational speed to 1500 RPM at the start of the compressor, turn off the operation of the freezer blower, turn the blower for the refrigerating compartment to rotate at low speed, and open the electric damper. Thus, it refers to an operation for saving energy by cooling the refrigerator compartment by blowing it to the refrigerator compartment for a predetermined time until the cooler is cooled.

The frost cooling operation means that when the compressor is stopped, the electric damper is opened, the freezer blower is turned off, and the refrigerator blower is operated to cool the cold air cooled by latent heat of frost attached to the cooler. It is operation to blow and cool a refrigerating compartment.

As a result, the refrigerator compartment can be cooled by using latent heat of frost attached to the cooler, so that a refrigerator having high energy saving performance is obtained.

Further, by cooling the cold air cooled by the latent heat of frost to the refrigerating chamber, the cooler is defrosted and the blowing of the cold air to the refrigerating chamber is stopped at a timing at which the defrost is almost completed. That is, in the case where the frost attached to the cooler is reduced to the predetermined amount or less, when the cooling temperature is lower than the predetermined refrigerator temperature, the blowing of cold air to the refrigerator compartment is stopped, and when the refrigerator compartment temperature is higher than or equal to the predetermined temperature, The compressor is operated while continuing to blow.

By the configuration of the embodiment described above, the following effects are obtained.

That is, a heat insulation partition wall partitioning the freezer compartment and the refrigerating compartment, a freezer compartment door for opening and closing the freezer compartment, a refrigerating compartment door for opening and closing the refrigerating compartment, a cooler compartment partitioned from the freezer compartment at the rear side of the freezer compartment, and the cooler compartment A refrigerator having a cooler disposed therein, a freezer blower and a refrigerating chamber blower disposed in the cooler chamber, and a cold air passage for sending cold air from the cooler chamber to the refrigerating chamber, wherein the cold air passage is rearward in the adiabatic partition wall. The cold air formed forward from the portion and blown by the refrigerator compartment blower is blown downward from the upper part of the storage unit (door pocket) provided in the refrigerator compartment door from the first outlet of the front portion of the cold passage. .

Thereby, the food of the front part of a refrigerator compartment and the food accommodated in the door pocket can be cooled quickly, and the preservation | saving property of the food in a refrigerator compartment can also be improved.

Furthermore, the time to cool the beverage in a water storage tank with a large heat capacity can be shortened.

Moreover, since each chamber can be cooled by an independent blower, it is easy to perform temperature setting and optimal cooling. Moreover, even if a refrigerator becomes large and a cooler room becomes large in width compared with the width of a cooler, since a ventilation duct is comprised using the space as much as this width dimension becomes large, the refrigerator which does not increase an invalid space is obtained. .

In addition, a cold air is blown into the freezer compartment and the refrigerating compartment by a freezer blower, a refrigerator for the refrigerating compartment, and the like to form a refrigerator that independently cools both chambers. Thereby, it can be set as the refrigerator which can quickly cool the beverage in the water storage tank accommodated in a door pocket.

The blower duct is also connected to a second cold air passage that ejects cold air from the rear side of the refrigerating chamber. Thereby, since the food in a refrigerator compartment is cooled from the front side upper side and the back of a refrigerator compartment, cold air flows easily to the place where cold air is hard to reach, and the preservation of food is improved.

Moreover, the electric damper which adjusts the amount of cold air blown by a cold air path etc. was provided in the middle of a blowing duct. As a result, the back plate portion in the refrigerating chamber is flattened, the shelf area is increased, and the actual storage amount can be increased, thereby increasing the volumetric efficiency.

The cold air passage is connected to a second cold air passage having a second jet port for ejecting cold air from the rear side of the refrigerating compartment into the refrigerating compartment. A return passage for returning the cold air ejected from the first jet port and the cold air jetted from the second jet port to the cooler chamber was provided in the rear side of the refrigerating chamber.

As a result, after heat-exchanging with the storage part (door pocket part) and the refrigerating compartment, the food stored in the door pocket part and the beverage in the reservoir tank are quickly cooled, and the food stored in the refrigerating compartment is located above the front side of the refrigerating compartment. And since it cools uniformly by cold air blown off from the back surface, the shelf life of food is improved. In the case where a large heat capacity such as a water storage tank is arranged in the door pocket, the water tank in the water storage tank is rapidly cooled, and other foods stored in the door pocket can be quickly cooled. It cools down quickly and can raise a user's satisfaction.

In addition, a return passage for returning the cold air ejected from the first jet port and the cold air jetted from the second jet port to the cooler chamber has passed through a gap passage between the container provided in the lower part of the refrigerating chamber and the bottom surface of the refrigerating chamber. It was installed in the back side of the refrigerating chamber so that cold air flowed.

In this way, the cool air from the front side upward flows and cools along the surface of the front part side of a container, and the cool air from the back part flows and cools along the container surface from the rear part side of a container, and the cold and back part from these front side upper parts are cooled. By cooling from the cold air, the entire container is cooled, so that the temperature of the entire container can be made uniform. Thereby, the frost adhesion which arises in part by the temperature difference inside a container can be suppressed. By indirectly cooling the inside of the container by cold air provided at the bottom of the refrigerating chamber and cold air flowing over the upper surface of the container, food such as vegetables is prevented from being dried or cooling of the cold partly directly. It can be set as a container suitable for.

In addition, the freezer blower and the refrigerating chamber blower installed in the cooler chamber are located at the upper part of the cooler, and both blowers suck cold air that passes through the cooler, and the cooler blower is configured to eject cold air toward the door pocket and the refrigerating chamber. .

As a result, the refrigerating chamber can be cooled by using latent heat of frost attached to the cooler, whereby a refrigerator having energy saving can be obtained.

In addition, a space having a gap of 5 to 10 mm between the front face of the cooler and the partition plate and between the cooler and the inner box is formed in approximately the entire area of the lower part of the cooler to eliminate the deviation of the idea of distribution.

Thereby, even in the refrigerator of the large freezer in which the quantity of cold air to a refrigerator compartment increases, even if one part generate | occur | produces a little early frost by the return cold of some refrigerator compartments, the refrigerator which does not lose the function of the whole refrigerator is obtained.

In addition, when the compressor is stopped, the cold air cooled by the latent heat of frost attached to the cooler is operated, and the upper part of the refrigerating compartment door pocket 7 located below the outlet port 18b of the front portion of the cold passage. Cool air was blown out in the direction, and the cold air was passed through the cold air passage 24 on the rear side of the refrigerating chamber to blow cold air from the jet port 25a toward the refrigerating chamber to cool the refrigerating chamber.

Thereby, for example, to cool the refrigerating compartment, the refrigerating compartment can be cooled by using latent heat of frost attached to the cooler, thereby obtaining a refrigerator in which energy saving is achieved. In addition, since the cool air is ejected and cooled in the upper direction of the refrigerating compartment door pocket 7 from the blower opening 18b close to the refrigerating compartment door pocket 7, heat outside the refrigerator is heat-conducted from a portion where the door and the refrigerator are in contact with each other. Even if (7) and this vicinity are heated, temperature rise can be prevented or suppressed.

In addition, when the frost attached to the cooler decreases below a predetermined amount, when the frost attached to the cooler decreases below a predetermined amount, while cooling the refrigerating compartment with the cold cooled by the latent heat of frost, when the temperature falls below a predetermined refrigerating compartment temperature, When the cooling of the cold air is stopped and the refrigerating chamber temperature is higher than or equal to the predetermined temperature, the compressor is operated while the blowing to the refrigerating chamber is continued.

Thereby, the energy saving performance is high, the food in a refrigerator compartment can be maintained in the range of predetermined | prescribed temperature, and a reliable refrigerator can be provided.

That is, according to the structure of each embodiment, the said air flow path is connected to the cold air passage formed toward the front from the rear part in a heat insulation partition wall, and the cold air blown by the refrigerator compartment blower is opened from the opening of the front part of a cold air passage. Since the cold air is ejected in the upper direction, the food in the front part of the refrigerator compartment and the food stored in the door pocket can be cooled quickly, and the preservation of food in the refrigerator compartment can also be improved.
